Is there an image i don’t understand what expressions you’re asking for?
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)
Further explanation:
Given sequence is:
3, -6, 12, -24, ...
We have to find the common ratio first.
Common ratio is the ratio between two consecutive terms of a geometric sequence.
It is denoted by r.
So,

General formula for geometric sequence is:

Putting the values of a1 and r

Hence,
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)

Answer:
y = |x| + 3.
Step-by-step explanation:
The movement of the y value from 1 to 4 is a translation of 3 units upwards.
The graph is y = |x| + 3.
3*3+4*4=x*x and 9+16=25 so x is 5 and then add other sides so 5+8+4+5
Answer:
The number line on the top right
Step-by-step explanation:
Her solution should be
2x - 14 ≤ 8
x ≤ 22
x ≤ 11
'x' is less than or equal to 11.
